Cascade is our adventure bike - rugged drop bar radness. bikepacking, gravel, dirt.

The Cotic Cascade is our brand new drop bar adventurer. We designed it to have the fewest compromises so you can go the furthest. It drops neatly into that space between our super capable SolarisMAX hardtail mountain bike and our road/gravel Escapade. Cascade surfs around the grey area between tarmac and trail with the kind of progressive, confident handling you would expect from Cotic. If you’ve ridden, pushed and sweated your bike to the top of a mountain, you’re going to want to be able to ride down the other side.

Cascade has a chameleon character born of it’s ability to wear all sorts of build options. From stripped down desert racer with carbon rigid forks, through overlander with our bespoke steel fork and custom fit luggage, to drop bar mountain bike with 100mm suspension forks and a dropper, and any combination of the above. It wears any of these build with panache, and it is just as comfortable travelling for days through wide open spaces as it is snicking down your favourite local singletrack for a quick hour blast.

Ultimately, we’re coming at “gravel" from the MTB side, so when we get to a downhill we want the option to drop the seat, drop our heels, and crack on. The Cascade allows you to do that. It’s the off road connoisseurs drop bar bicycle.

Read UKGravelCO's review of the Cascade:

"So who is this bike for? Firstly anyone who wants to put a massive grin on their face, the bike is so much fun!"

"If you have never ridden a drop bar bike and are coming from an MTB back round you will feel right at home. If you have never ridden off road and want to leave the tarmac to dabble in the dirtside, then this bike will flatter and cosset you while you hone your new found skills riding the trails."

"So, Cotic Cascade: Drop bar MTB or gravel bike? Who cares! Throw your leg over one and pedal off with the biggest grin you’ve had on your face for a long time!"

Read Bikeperfect's 4/5 review of the Cascade:

"And while some of you will be here for the tire and baggage bolting versatility and others for the slim steel aesthetics, handling is undoubtedly one of the best of many great aspects of the Cascade."

"Having a dropper post that can be triggered remotely from the drops is also a big enabler when it comes to getting down and dirty."

The chart is a guide to frame size for the Cascade: Sureshot Geometry means that the frames are long and stems are short (typically 60mm). You'll need at least a 350mm seatpost due to the frames having space for dropper posts. The road bike style sizing shown, eg 54 for Small, is simply a guide to riders used to road bike sizing as to which frame size to choose. Drop us a line at and we'll be happy to discuss size and set up based on what you're riding at the moment.

Bikes are now available worldwide, with free shipping to UK, Ireland and mainland Europe.

We have several levels of stock build which are based around our favourite parts in builds you can trust. We never specify anything we haven't ridden, tested and enjoyed. However, just about everything in your build can be customised to help with fit (contact us if you need help) or to personalise your bike. Want a different fork? Shock? Brakes? Wheels? Tyres? Bars? Stem? Longer drop seatpost? Women's saddle? Colour matched Hope components? No problem. It's your bike.


All the bikes are assembled from a frame right here in the UK by us. We can do everything from bare frame to complete bike: Send us your favourite saddle and grips to fit. Send us your wheels if you have a nice pair you want to use. There's no point you getting kit you don't want. It's wasteful. That gives you almost limitless options to customise and tune your bike to your needs. If you can't see an option you'd like on the order form, get in touch. We all know it's good to head off piste sometimes!

Tap on a build title below to see the default specification and price for that build... then hit the 'CONFIGURE YOUR BIKE' button to see all the customisations you can make to the build. When you select your country at the bottom of the form, sales taxes (VAT), pricing and shipping will automatically update for you. Once you're happy, order your bike!

Features and Benefits
Sureshot Geometry

The Cascade has our new Sureshot geometry. This takes all the principles that makes our Longshot mountain bike geometry so good and tailors it to drop bars. Long top tubes, short stems and slack head angles aren't just for mountain bikes. Wide and flared drop bars give you multiple hand positions for maximum comfort and stability all day, while 60-70mm stems keep the handling pin sharp for big grins.

Plenty of room for luggage in the spacious front triangle, while still allowing enough clearance for a dropper post for every rider, so you can really get the most out of SureShot geometry and your Cascade.

For those looking to put flat or MTB bars on the Cascade, it is possible and you can mount post mount brakes with specific fittings. Click on the Component Sizes tab below for full details.

Reynolds 853

Reynolds 853 builds a light, lively and fantastically robust front end, and includes our custom ride tuned Ovalform top tube which helps to deliver that famous ride feel. The frames' steel construction is compliant and naturally ground moulding, extracting grip and feedback from the trail where you thought there was none. Pair it to our custom sized and shaped heat treated cromoly rear end for the lightest, toughest, most beautiful riding frame.

Cotic Alpaca Fork

The Cascade features our all new Cotic Alpaca fork. It’s a taper steerer, heat treated cromoly wonder with so many fittings and features. 3 bolt Anything Cage on both legs, micro-rack, fender bosses, low rider mounts. Internal dynamo routing. Boost110 x 15 thru axle and Flat Mount +20 brake mount for up to 180mm front rotors. Smooth riding, clean lines, multi function.

If you want to lighten things up, we have the Salsa Firestarter 110 carbon fork as an option, or the RockShox SID Race Day Ultimate 100mm suspension forks for full dirt road bombing.

Boost Spacing - 1x Drivetrain

The Cascade is for off road riding and uses 29” wheels, so it features mountain bike style Boost110 front and Boost148 rear hub spacing for robust wheels. 53mm Boost chainline 1x dedicated design continues the simple, reliable theme.

Big Clearance Design

Cascade is a dirt bike with drop bars, so it needs proper tyres. It’s native designed for upt to 29 x 2.4” tyres at the rear, and up to 29 x 2.6 at the front. This does mean you can fit 27.5” x 2.8” rear / 27.5 x 3.0" front should you so wish, but those 29ers are where it’s at for all round performance.

Custom Luggage

As part of the development of this most adventurous of adventure bikes, we have designed a perfectly fitted frame bag. Handmade in the UK, it’s a stable and secure lace up fit, with a removable flouro liner making the interior easy to see, and easy to remove on those cafe stops.

All the fittings: Racks, Mudguards/Fenders, Cages, Luggage

There are bosses all over the Cascade frame and Alpaca fork. Most of these are in the main front triangle and are spaced at 64mm bottle boss spacing, so you have maximum flexibility in loading your bike. You can fit 2 bottles on the down tube, a bottle and an "Anything Cage", and pretty much anything else with bottle boss mounting. The possibilities are endless. These also double up as the hose routing bosses on the down tube.

Mounts for full length mudguards/fenders are present on both the frame and fork.

There are 3 boss "Anything Cage" mounts under the down tube, under the top tube and on either side of the Alpaca fork.

On the Alpaca fork and the rear triangle there are rack mounts for full racks front and rear, lowrider racks on the fork, and there are bosses halfway up the seatstay and fork leg for mounting mini racks like the Nitto M18 either front or rear.

Cascade and Alpaca have got you covered for luggage.

We Build Your Bike For You

All Cotic bikes are assembled in the UK from and frame up. We have set specifications, but these are just the start. If it's not a choice on the order form, just ask. We have a bunch of wheel options from Hope and HUNT, tyre options from WTB and Wolfpack, and many more things to make your Cascade your own.

When you contact us you are talking to the people who design the frames and will be building your bike. We check it and build and pack it in our award winning bike boxes with the same care we would our own bike, because we know how important it is.

We build your bike, for you.

Is the Cascade the bike for you?

Like the idea of the Cascade, but want a lighter, more road bike sensibility? Have a look at the Escapade.

Maybe you want a more dedicated off road machine, but still with options for some luggage and plenty of cages? Check our the SolarisMAX.


Cotic frames are designed, developed, engineered and tested entirely by us at our base in the Peak District, near Sheffield in the UK. Our founder - Cy Turner - is the lead designer and engineer, and our frames are rigorously ride tested by everyone at Cotic, and our Race Team. They are fully certified and lab tested in excess of the requirements of ISO4210 safety standards.

This frame is hand made in Taiwan by our specially selected framebuilder, chosen because of their vast experience with our favourite materials, and their top quality finish. They are the best in Taiwan for what we need.

Each frame is dip coated inside and out with zinc phosphate before painting, to prevent corrosion and ensure the best paint finish. After we've agonised over the colours, designs and decals the frames are painted to the highest quality including a protective clear coat, before extensive QC by our agent in Taiwan. Once the frames reach us in the UK, we carry out further QC, and prep the frames for headset and bottom bracket installation.

As always, all complete bikes are built to order by us here in the Peak District, to the exact spec of your choice. We build your bike for you.
